한국산 박쥐나물속(Parasenecio)의 외부형태학적 형질 및 체세포 염색재수의 분류학적 가치를 평가하기 위하여 본 연구를 수행하였다. 외부형태학적 형질인 초장, 경생엽수, 잎의 모양, 엽병 형태, 총포편수, 소화 수, 암술대의 털 존재 유무, 소화의 가는 통부와 법은 통부의 비, 열매의 크기 등이 종을 식별하는 형질로 가치를 지니고 있었으며, 이러한 형질을 기초로 할 때, 귀박쥐나물(Parasenecio. auriculata var. auriculata), 나래 박쥐나물(P. auriculata var. kamtschatica), 민박쥐나물(P. hastata subsp. orientalis), 참나래박쥐(P. koraiensis), 병풍쌈(P. firmus), 어리병풍(P. pseudotaimingasa)의 6분류 군에 대한 국내의 분포를 확인할 수 있었으나, 게박쥐나물(P. adenastylodes)과 박쥐나물(P. auriculata var. matsumurana)의 분류학적 위치 및 국내 분포 여부에 대하여 추후 연구되어야 할 것으로 생각되었다. 게박쥐나물과 귀박쥐나물, 나래박쥐나물, 민박쥐나물, 병풍함과 어리평풍의 체세포 염색제수는 모두 2n=60이었으며, 이중 게박쥐나물과 귀박쥐나물, 나래박쥐나물, 민박쥐나물은 일본산과 중국산의 염색계수와 일치하였으며, 병풍쌈과 어리병풍의 체세포 염색체수는 본 연구에서 처음으로 밝혀졌다.

섬유에 대한 plasma 처리의 process상 특징은, 첫째 건식공정 둘째 간략화된 가공, 이라고 하는 두 가지 특징을 들 수 있다. 일반적인 섬유가공에서는 처리시에 대량의 물이라든지, 증기를 사용하고, 또 다량의 열 energy를 표하기 때문에, plasma 처리와 같은 기상처리기술에 대한 기대가 그 무엇보다 크다. 만약, 종래의 습식공정에 의한 섬유가공공정의 전부나, 일부를, 이 건식방법인 plasma공정으로 바꿀 수만 있다면 절수라든지, energy절약에도 크게 이바지하여, 경제적인 효과가 클 뿐아니라, 염료와 염색조제들을 위시한, 가공처리제 등의 사용량도 크게 줄일 수 있어서, 공해의 미연방지에도 크게 이바지하게 될 것이다.

The purpose of this study is to examine the difference between service quality satisfactions according to tourists' preference and segmentation by various motivations. Data were collected from 442 farm stay visitors by field surveys in rural areas. A factor-clustering method identified three distinct segments; want-it-all, overall low motivation, relaxation. MANOVA was used to examine the differences of service quality satisfaction for farm stay visitors' preference and segmentation by motivation. Results show that the type of guest room more significantly influenced farm stay visitors' satisfaction according to those three clusters. It should be noted that we have information on the characteristics and type of satisfaction of the consumers in order to improve the quality of farmstay's service in rural tourism.

Recently the package design for agricultural product of farm stay is great interests for increasing the income of farmers and villages as it may fulfill the sensible needs of consumers who experience rural culture and farm stay. This paper presents the status of the package design for agricultural product of farm stay and proposed improvements to the package design as following; 1)to diversify the packaging capacity, 2)to develop the cultural products to applicate the traditional crafts technique, 3)to provide institutional strategies for presenting the identity of farm or village, 4)to develop the education program about package design. We sampled fifty pilot farms or villages, analyse the package design of them and questionnaire surveyed farmers and managers in order to find problems and suggest improvements.

This study focuses on analyzing the present conditions of homestay in Donghae, which helps to increase the fishing and agrarian villages' income and offer a low-priced lodging facility to tourists. Furthmore it tries to find the related problems and to suggest the solutions. For this purpose, homestsy businesses in Donghae city was surveyed by the questionnaire. Frequency analysis and Cross table analysis of the collected 97 questionnaries were conducted by the SPSS, and the related problems were found as follows. After homestay business turned to the liberal business, professional homestay businessmen appeared and conflicts between farmer and professional businessman came out. And there's a limitation on providing subsidiary facilities and services for the local businesses because of their financial difficulty and on-off season. Therefore to develop “fishing and agrarian villages' homestay businesses” well-defined standards of homestay is required. Then to provide subsidiary facility, services and special programs activation of homestay association is necessary. Finally, to attract tourists, local government's tourist attraction policy is needed.

의용 초음파 장비는 X-Ray, CT, MRI 등 다른 의료 장비보다 휴대성과 안전성면에서는 장점이 있지만 진단 시 해상도와 화질 저하를 유발하는 스펙클이 생기는 단점이 있다. 그러나 단순한 스펙클 잡음의 제거는 경계선 정보의 손실을 발생시킬 수도 있다. 이에 본 논문에서는 효과적인 스펙클 제거와 손실 없는 경계선 검출을 위해 뉴럴네트워크와 퍼지 클러스터링을 이용한 뉴로-퍼지 스펙클 제거 방법을 제안하였다. 제안된 방법은 입력된 의용 초음파 영상에 대해 먼저 퍼지 클러스터링을 적용하여 세 영역으로 나누고 이후 각 영역별로 별도의 뉴럴 네트워크를 적용하는 방법이다. 실제 실험 및 기존 방법들과의 정성적?정량적 비교 분석을 통해 제안 방법의 유용성을 검증하였다.

To find the anti-Alzheimer's activity of Cacalia hastata var. orientalis (Compositae), caffeoylquinic acids were analyzed in this plant by HPLC and the inhibitory activities of the extract on cholinesterases including acetylcholinesterase (AChE) and butyrylcholinesterse (BChE) and peroxynitrite ($ONOO^-$) were assayed. Sum of caffeoylquinic acids in the 80% MeOH extract was quantitatively higher in leaves (35.8% of the extract) than in stems (3.7%). The compound, 3,5-dicaffeoylquinic acid, was contained in the highest amount in the leaf (44.32 mg/g dry weight). The $IC_{50}s$ of the 80% MeOH extract were shown to be $67.45{\mu}g/ml$ for AChE, and $8.59{\mu}g/ml$ (for $ONOO^-$), respectively, suggesting that the leaves would have the anti-Alzheimer's activity due to the high content of caffeoylquinic acids.

The purpose of this study was to explore the situations of farm stay and visit's perceptions in rural Korea. The data were collected by questionnaire and case study, and obtained from 104 visitors, 104 host farmers, 104 village people in twenty two rural villages from September 20, 2002 to November 21, 2002 and analyzed by SPSS WIN 10. The statistical method was crosstabulation and chi-square. The major findings of this study were as follows; First, the priorities of government policy for farm stay were to build the physical infrastructure such as village road and parking lot, to help farmers make relations with urban people, and to provide the learning opportunities for their business. Second, the main barriers for farm stay were the deficit for improving their facilities. And the income within their farm stay has been low at government policy village. Third, most of host farmers liked to make relations with their village people. The priorities of their relations were to improve natural and social environment of their villages, to develop the special brands, and to manage village tourism programs.

The purpose of this research is to investigate the characteristics of Jeju recreational pension. This research is carried out by on site inspection and the survey on management of the recreation facilities. A target of research is sixteen facilities of recreation pension in Jeju-do. Recreational pension was created by Jeju Free International City of special law in 2000. Jeju Recreational pension has characteristics as follows : The land area of that is $1300m^{2}{\sim}6300m^{2}$, the number of guest rooms are 10, and the area of guest rooms are $29m^{2}{\sim}100m^{2}$. Especially most of them are in Namjeju-gun. Also, they mostly have R.C. structure, and materials of exterior are artificiality stone. The color of an outer walls are mostly white and light-beige and that of the roofs are mainly dark-brown. On plot plan, it has 4type of prototype; type of outbuilding, arranging in a row, corridor, hall and composition of three types with public area. The outside facilities are equipped by handy golf courses and outdoor barbecue cooking sites. Unfortunately, most of pensions don't reflect the characteristics of architecture factors in Jeju.
